Habitat:
Taken in 5-570 m; occasionally found as a beach shell. Rare in NSW.

Comparison:
This species has smooth spiral ribs, in contrast to the beaded ribs of C.
comptum.Calliostoma excultum (Iredale, 1931), known only
from the holotype (type locality: off Disaster Bay, NSW, in about 50
fms), is close to C. legrandi, but differs by having more
numerous spiral threads and by having red-brown dashes on some of the
threads of the last whorl.
